Description

Technical Field

[0001] This utility model relates to the field of bearings, specifically a bearing that is easy to install. Background Technology

[0002] Bearings are typically mounted on shafts to support the rotation of mechanical structures and reduce the coefficient of friction generated during rotation. During installation, the bearing is usually moved slowly to its mounting position by an operator using a rubber mallet to strike it. When installing a bearing on a long shaft, the higher side of the bearing is repeatedly struck to move it evenly. However, during this movement, the inner ring of the bearing may tilt relative to the shaft, causing the bearing to seize up. Furthermore, excessive hammering force can damage the bearing's structure. Utility Model Content

[0003] The present invention aims to provide a bearing that is easy to install, so as to facilitate the installation of the bearing by the operator.

[0004] To solve the above technical problems, the specific solution adopted by this utility model is as follows:

[0005] An easy-to-install bearing includes symmetrically arranged slots on the inner ring of the bearing, a slidably connected positioning block in the slot, a fixing rod extending upward from the top of the positioning block for the operator to strike, and locking blocks extending into the slot on both sides of the positioning block.

[0006] The length of the positioning block is less than the distance between the inner and outer rings of the bearing.

[0007] A reinforcing rib is provided between the fixing rod and the positioning block.

[0008] The bottom of the card slot does not penetrate the bottom of the inner ring, and the side slot of the card slot is convex in shape.

[0009] An extension rod is fitted onto the top of the fixing rod, and a slot is provided at the bottom of the extension rod for the fixing rod to be inserted.

[0010] Due to the adoption of the above technical solution, this utility model has the following beneficial effects:

[0011] By setting a groove on the inner ring of the bearing and a slidable and removable positioning block inside the groove, and a fixing rod on the top of the positioning block for the operator to strike, the bearing can fall evenly when the operator strikes both fixing rods simultaneously with a rubber hammer, preventing the hammer from hitting the top of the shaft. This protects the bearing structure and reduces the occurrence of bearing jamming with the shaft. This invention has a simple and reasonable structure, effectively protects the bearing structure, and reduces the occurrence of bearing jamming with the shaft. Attached Figure Description

[0016] like Figures 1-3 As shown, an easy-to-install bearing includes symmetrically arranged grooves 2 on the inner ring 1 of the bearing. The grooves 2 are parallel and symmetrical, and the bottom of the grooves 2 does not penetrate the bottom of the inner ring 1. The side of the grooves 2 has a convex groove. The grooves 2 are provided with slidingly connected positioning blocks 4. During installation, the positioning blocks 4 are inserted into the grooves 2 along the side of the grooves 2. The top of the positioning blocks 4 is provided with an upwardly extending fixing rod 3 for the operator to strike. Since some shafts are too high to be hammered into place properly, the extended fixing rod 3 facilitates the operator to strike them into place. The length of the positioning blocks 4 is less than the distance between the inner ring 1 and the outer ring of the bearing, so that after use, the positioning blocks 4 can be slid out along the grooves 2 and removed. The two sides of the positioning blocks 4 are provided with locking blocks 5 extending into the two sides of the grooves 2. The purpose of the locking blocks 5 is to position the positioning blocks 4. The fixing rod 3 and the positioning blocks 4 are provided with reinforcing ribs 6, which make the fixing rod 3 more durable.

[0017] An extension rod (not shown in the figure) is fitted on the top of the fixing rod 3, and a slot is provided at the bottom of the extension rod for the fixing rod 3 to be inserted. When used with a longer shaft, the extension rod can be added.

[0018] The method of using this utility model is briefly described as follows:

[0019] When mounting a bearing on a long shaft, first place the bearing onto the shaft, then hammer the bearing into position by striking the top of the fixing rod 3. During hammering, the rubber hammer strikes the tops of the two fixing rods 3, ensuring even downward force and avoiding the traditional method of hammering the higher side sequentially, which can easily cause the bearing to seize up and damage the bearing's structure. Once the bearing is in place, installation is complete by sliding the positioning block 4 along the slot 2.
